OpenSUSE Install :: Fsck - Not Needed With Ext4 Filesystems?
Apr 17, 2010
My openSUSE 11.2 system has periodic running of fsck disabled for ext4 filesystems (Maximum mount count = -1, Check interval = 0). What is the reason for this? Is it because fsck is not necessary on a periodic basis with ext4, and only necessary when errors are detected? Or is it because fsck has problems working on ext4 filesystems?
The ext3 filesystems do have it set (Maximum mount count = 500, Check interval = 5184000 (2 months)). I would like to know why fsck is not set to be activated for ext4.

I want the filesystem of my external drive to be checked periodically after a numer of mounts. I put 2 in the sixth colums of fstab for this partition
Code:
/dev/sdb1/mnt/hdext3rw,dev,sync,user,noauto,exec,suid02
and I use the tune2fs to set the maximum mount count to 32.
Code:
tune2fs -c 32 /dev/sdb
now the mount count is 34 and the date of the last check is not recent, so apparently the auto fsck has not been performed. Probably because this partition is not mounted at start-up but I usually mount it manually.

I am attempting to run a fsck on a number of large ext3 filesystems. I am doing this proactively because I want to minimize reboot time and the filesystems are past the interval time of 6 months. When I run the command " fsck -f -y device" I get the following error on all of the filesystems-
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
fsck.ext3: Device or resource busy while trying to open /dev/mapper/mpath0p1

I have 3 partitions, all NTFS filesystems, I want to keep them, but change the filesystems on all 3 of them to Ext4. So if i choose "Erase and use all" will I be able to partition later? I'm thinking more about doing like this, but I'm not sure : First partition as my main, system partition, is this correct?

I go to bed and my computer is fine and working. I come home from work, no signs of a power outage, and my computer has errors regarding a corrupt disk. Drops to Cmd prompt. My problem is that I want to do the proper recovery on it, and my googling doesn't seem to help. All I see is stuff about how FAST fsck is, but no one wants to talk about how to use it. Besides, I better check with people before I mess everything up.
I have the FC12 install disk I used loaded up now, at the cmd prompt. I have my system mounted, an EXT4 LVM. Do I unmount and then run fsdk.ext4 -fp /dev/mapper/vg_mysys-lv_home ? (lv_home is the one reported as corrupt during boot)

Seems like I misplaced this topic. Should have been in general help. Sorry! Any moderator feel free to move this topic. As I was creating a swap partition, something went wrong and I ended creating a much bigger file which consumed all my empty space. Ubuntu stopped working and now I can't seem to fsck / mount my disk. Currently I'm on a live cd. fsck will give:
Code:
e2fsck 1.41.12 (17-May-2010)
fsck.ext4: Device or resource busy while trying to open /dev/sda2
Filesystem mounted or opened exclusively by another program?
However, the file system is not mounted.

I am building a minimized 6.2.2 linux kernel using slackware on a dinosaur of a computer: AMD Athlon +1700 Single Core processor, 1gig of DDR SDRAM. This is my first time compiling a linux kernel, so before I make any major mistakes, I could use some help in determining which filesystems I absolutely must enable support for. Ext2 is allready in.

I have $ uname -a
Linux kub 2.6.32-5-amd64 #1 SMP Mon Mar 7 21:35:22 UTC 2011 x86_64 GNU/Linux
Most of the time when I boot my PC I get an error about fsck.ext4: Unable to resolve... I don't know why it's happening.
The problem is happening with my external drive that has 3 partitions:
/dev/sdc1
/dev/sdc3
/dev/sdc2
About 90% of the time I boot I do get the error. Sometimes after getting the error I can login and the external drive (/dev/sdc) is already mounted:
$ df -H
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 15G 8.0G 5.8G 58% /
tmpfs 1.9G 0 1.9G 0% /lib/init/rw
udev 1.9G 246k 1.9G 1% /dev
tmpfs 1.9G 738k 1.9G 1% /dev/shm
code....
The UUID's in the error file match the output of the command blkid. And the UID's of blkid match the fstab UUID's. I don't know what to do at this point.

I have a mysterious filesystem issue with openSUSE on an old machine. Installation wasn't very pleasant but worked finally. It boots fine. However after 5 or 10 minutes, all filesystems vanish. Most programs (but not all) cannot be found anymore. "ls" output is empty everywhere. "top" used to work (it was working on a ssh connection that I just lost). Now it complains about unset TERM variable. I was able to set it again to xterm. Now "top" is working, displays the running processes : mysqld, Xorg, icewm (my WM), nothing strange there, nobody is eating up the resources. I have other linux installed on that machine : Ubuntu freezes occasionally, mostly with Gnome, but it seems to be a totally different problem (maybe related to the radeon driver) ; Mandriva works fine so far. The two IBM 120 GB harddrives are quite old but the manufacturer fitness test didn't find failures. I also checked for bad sectors before formating in openSUSE setup. It doesn't look like a physical I/O problem. In such a case, it would crash or at least complain about not being able to access the HD. Well ... I switched to console but I didn't get any login prompt and now I cannot switch back to X. I can still ping the machine but of course not ssh to it. SysReq keys (although enabled) doesn't work. I guess I will have to reboot brutally. Last time it took me about one houre of pressing 'y' tp repair the filesystem with Ubuntu. I'm sure I will be back soon. What do you guys think about that situation ? I suspect a kernel issue with that hardware. Have you heard about similar problems ? I'm afraid I will have to reinstall 11.1, which used to work fine, on that machine.
Some details about the hardware : The (onboard) Promise controller and the SATA controller are not used. The 2 HD are on the first IDE interface as master and slave.

I am looking for a solution to administer my remote server running SUSE LINUX 10.1 (X86-64) - Kernel 2.6.16.13-4-smp. I have made changes to server and is able to see the boot process and also able to login to system through serial console.
My question, will I be able to administer the server through serial console incase if my root partition is corrupted and system has gone to maintenance shell(or root shell).
Also is there way to go directly to maintenance shell from grub(not talking about single user mode). I want to go maintenance shell where / partition is not mounted.

Sorry if it is a dumb question (i'm coming from deb/ubuntu and i'm totally new to rpm - installed Smeegol on a Samsung N150). After some try&error i finally got my Broadcom4313 working but underway to that i got lots of new kernels and now i don't understand not so much anymore.
I think the kernel default-devel it was me installing it using the distribution manager to get working make (for trying to install the original Broadcom driver package; i stopped that attempt because i didn't where exactly to move/cp the built driver).

After installing the recent kernel update and rebooting my machine I have found a horrible fact, my computer won't boot anymore. It seems my root partition was corrupted, and running fsck on it just sends me through a endless loop of "Ignore Errors {y}:" and "Force overwrite {y}:". I have already tried the use the repair system on the installation DVD but that doesn't do anything, the pop up asking if I want to repair the file system keeps coming up when I click repair.

I was unable to boot into my system after I'd just shut it down, so I tried repairing it using my installation media... only to find that though my root Ext4 fs on sda6 was corrupted & *supposedly* repairable, the cd could not do so for some reason! All I can get is a command line, saying something about the root fs being mounted as read only, and I have no idea how to resolve this. I cannot afford to loose ANY of the data I have on here.

I have done it quite often. Inserted and run the computer from a live CD so that the hard drive is not mounted an changed the partitions. It worked on the old reiserfs when I wiped the windows partition on my laptop to increase the space, it worked on ext3 partitions. Now I resized the swap partition and reduced the NTFS partition on my desktop - no problem. But it does not increase the ext4 partition. No error message it just does not do it. I tried several times with the suggested maximal setting, with a custom setting, etc. It just does not change size. Just for interest I booted into Suse11.0 live CD and tried from there. There I get the answer cannot resize partition as the file system does not allow resizing. Is something wrong with the system or does the partitioner not work with ext4?

I have a system running OpenSUSE 11.3 using the bare server configuration.I had a partition for my /srv directory. All was fine until earlier today. I shutdown my system (to remove an old floppy drive from it). When I rebooted, /srv is emtpy (no files nor directories). This is somewhat vexing, as I had several sites running from there, as well as a fair amount of data.The appropriate partition (/dev/sda3) appears using fdisk. However, there is no mention of it in /var/log/messages.Does anyone know how to recover an Ext4 partition?

I have a very simple question I am creating a new partition for storing files, installers, documents, etc, I am going to make it ext4, now my question is, do I have to specify a mounting point?? I would not like to do that, but if I do not specify a mounting point, will I be able to access that partition? So in what cases you specify mounting point and when you do not specify mounting point?

Tired of fat32 fragility, I reformatted a 4GB pen-drive as ext4 using Yast's partitioner. I chose format as ext4 and checked fstab options "can be mounted by user", "no access time" and "ordered journaling". I thought that these fstab options would be ineffective since a removable device won't be added to fstab. when I insert the pen-drive it auto-mounts and the folder /media/EMTEC is created (EMTEC is the volume name). The relevant mount entries are:
Code:
:~> cat /etc/fstab | grep sde
:~> cat /etc/mtab | grep sde
/dev/sde1 /media/EMTEC ext4 rw,nosuid,nodev,relatime,barrier=1,data=ordered 0 0
:~>
There's no fstab entry, as it should be, and there is a mtab entry corresponding to the pen-drive, /sde1. However the /media/EMTEC as created (by udev, I suppose) is owned by root, I can't write to it. But if I change (as root) the /etc/EMTEC folder permissions so it belongs to the regular user, i can (obviously) write to it *and* it stays so *between* remounts. Haven't tried a reboot yet. What I'm not sure is if ordered journaling is OK for a pen-drive - or any kind of journaling, for that matter. Or will this significantly decrease flash memory life? Also, the fstab options set in Yast appear to be remembered by whatever creates mtab, as well as /media/EMTEC permissions. Is that so? Where are these settings kept? How does this work?

I am dual booting OpenSUSE and Windows 7 Pro x64. Each OS is installed on a separate 1Tb hard drive. One question that I have tried to Google for a solution with no success is, how do you access ext4 from Windows? Shortly after I installed OpenSUSE, my OpenSUSE hard drive "vanished" from Windows 7. aturally, I can access all my hard drives from OpenSUSE, which does support the NTFS. I am quite sure that I am not the only person who has this problem as I know that dual booting Linux and Windows is quite common.

I installed opensuse 11.2 some 6 months ago as an alternative to windows 7, on a 44GB partition. Having become my primary OS, I am looking forward to expand the ext4 partition from 44GB to the maximum possible. I have some 24GB unpartitioned space, and free space on NTSF partitions (one of which could be deleted if necessary). What is the best and safest procedure to perform the partitioning.

I'm migrating my OpenSuse 11.3 (which was update from 11.2, 11.1 ........ ) to a new hard drive. My partitions were reiserfs and in the migration I'm "converting" them to ext4, the conversion process is simple and it works fine for all of them except the root one:
1) I create a new partition on the new hard disk (bigger than the original one)
2) I format it with ext4
3) I copy all the data with cp -a from the original partition to the new one
I already have all the partitions migrated to the second disk, then I have tried to do it with the root partition:
-I've booted with a system rescue CD and I've done !9 2) and 3) with no problems.
-I've edited and changed al entries in fstab and grub conf (menu.lst) to point the new partitions
-I've reinstalled grub and it seemed It will be no problems booting, but
It begins booting, the grub menu appears, It begins booting the kernel, but suddenly:
waiting for /dev/root to appear: OK
fsck.reiserfs -a /dev/sda2
........
mount -o ro,ad,user_xattr -t reiserfs /dev/root /root
and it fails, because sda2 is not reiserfs, but why does it try to mount it as reiserfs if I'm not saying anywhere it is reiserfs?
This is my fstab:
Code:
#/dev/disk/by-id/ata-ST3160211AS_6PT0V05Y-part2 / reiserfs acl,user_xattr 1 1
/dev/disk/by-id/ata-WDC_WD5000AADS-00S9B0_WD-WCAV91599607-part2 / ext4 acl,user_xattr 1 1
/dev/disk/by-id/ata-WDC_WD5000AADS-00S9B0_WD-WCAV91599607-part1 swap swap defaults 0 0
/dev/disk/by-id/ata-WDC_WD5000AADS-00S9B0_WD-WCAV91599607-part3 /home ext4 defaults 1 0
/dev/disk/by-id/ata-ST3500630A_9QG94AT1-part1 /mnt/backup auto noauto, defaults, users, exec .....
I've booted it also with SuperGrub2 disk and the same thing happened, so I think it's not a grub problem but I don't wknow why it tried to mount the root partition as reiserfs.
